Thanks Antique, the mechanic did mention that and was concerned that things may pop out. This information might convince him to try and repair the pump in situ.

Bongo is still 'hunting'

Post by pyroman » Wed Jan 31, 2007 11:12 pm

Hi all,

Well, my mechanic friend finally got his hands around the side of the pump (the side between it and the engine) and removed the two bolts to reveal a single "o" ring. Thanks Antique for the photos :wink:

Although not damaged or perished, he said it felt a little hard and therefore was not sealing properly. He replaced the "o" ring and the leak has stopped :D

But, the engine is still hunting!

Another guy at work seems to think it may be an air leak somewhere on the inlet manifold, anyone know of a similar diagnosis?

I really thought the "o" ring thingy would be it, but now I really am stuck and really don't fancy having to get the fuel injection pump removed. :cry:

you can usually "hear" an inlet manifold air leak. squirt some oil around the manifold/head gasket area with the engine running - if the engine note changes or smoothes out then robert's yer mother's brother.

hi sounds like fuel starvation, try a can of deisal connected straight to pump by pass filter and tank , before doing that start van,on top off deisal filter is the hand pump, try pumping that see if it gets better

antique - although my workshop manual says it has one, I did not find a priming pump on the top of my fuel filter housing. One of the threads on BF suggests that many Bongos are self priming i.e. no priming pump?

Yes Mike that's very true. The manual says the pump has a priming plunger on the top but mine is also self priming. Works too as I ran out of fuel on the testdrive #-o
